Eliglustat +/− Imiglucerase for Gaucher Disease
(ELIKIDS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety and effectiveness of a drug called eliglustat for children with Gaucher disease, a condition where certain fats accumulate due to a missing enzyme. Some participants will use eliglustat alone, while others will combine it with imiglucerase, an enzyme replacement therapy. Children who have been managing Gaucher disease for some time and are already on enzyme replacement therapy might be suitable candidates. The trial aims to determine if eliglustat can improve their health and quality of life. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, you must have been on enzyme replacement therapy for a certain period before joining, and you cannot have used substrate reduction therapy in the last 6 months.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that eliglustat is generally safe for patients with Gaucher disease. One study found that patients who took eliglustat for 4.5 years experienced significant health improvements and had few serious side effects. Another review of several trials with 393 patients found that any side effects were manageable and not life-threatening.
When combined with imiglucerase, studies indicate that this combination is also safe. No new safety issues appeared for children using both treatments together, suggesting that the combination does not increase the risk of side effects.
Overall, current research has shown that both eliglustat alone and with imiglucerase are safe options for treating Gaucher disease.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for Gaucher Disease because they offer new approaches to managing the condition. Most treatments for Gaucher Disease involve enzyme replacement therapy (ERT), like imiglucerase, which supplements the deficient enzyme in patients. Eliglustat, however, is a small molecule that inhibits the enzyme glucosylceramide synthase, reducing the production of the harmful substrate glucosylceramide, offering a different mechanism of action. Additionally, the combination of eliglustat with imiglucerase provides a novel treatment strategy that could enhance therapeutic outcomes by targeting the disease through both substrate reduction and enzyme replacement. These innovative approaches have the potential to improve patient outcomes by offering more tailored and possibly more effective treatment options.
What evidence suggests that this trial's treatments could be effective for Gaucher Disease?
Research has shown that eliglustat effectively treats Gaucher disease, a condition where fatty substances accumulate in certain organs. One study found that patients who took eliglustat for 8 years experienced a 69% reduction in spleen size and a 34% reduction in liver size. Their hemoglobin levels and platelet counts also improved, which are important for carrying oxygen and helping blood to clot. In this trial, some participants will receive eliglustat monotherapy, while others will receive a combination of eliglustat and imiglucerase. Research has found that eliglustat alone was just as effective as imiglucerase over 12 months. Patients also reported feeling less tired and having better overall health during treatment. This evidence suggests that eliglustat, with or without imiglucerase, shows promise in managing Gaucher disease.12678

What Are the Treatments Tested in This Trial?
Interventions
- Eliglustat GZ385660
- Imiglucerase GZ437843
Trial Overview
The study tests the safety and effects of Eliglustat alone, or combined with Imiglucerase in children with Gaucher Disease. It looks at how their bodies handle the drugs (pharmacokinetics), changes in their condition, and life quality.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Eliglustat plus imiglucerase for three years, at the dose of enzyme replacement therapy received before enrollment. After Week 52, Cohort 2 patients will switch to eliglustat monotherapy for the remainder of the study if the desired clinical response has been achieved.
Eliglustat for at least two years. Cohort 1 patients that experience significant clinical decline will receive rescue treatment. Rescue Treatment Step 1: Switch from eliglustat to imiglucerase monotherapy. Rescue Treatment Step 2: Patients who after 6 months of rescue therapy with imiglucerase monotherapy do not show improvement in the parameter(s) that led to the switch from eliglustat to imiglucerase, will then receive combination therapy with eliglustat + imiglucerase.
